Abstract
Description
- The present invention relates to a work vehicle having a fuel tank mounted upwardly of a vehicle wheel.
- As a fuel storing arrangement for use in a work vehicle described above, there is known an arrangement in which a fuel tank is provided with a bulging portion at a front end portion thereof in the fore-aft direction of the vehicle body, the bulging portion bulging downward so as to cover the wheel from above from the front side thereof (see, e.g. JP2004-236641).
- Recently, there has been a need for increase in the capacity for the fuel tank so as to achieve improvement in working efficiency through reduction in the number of refueling operations required. However, mere capacity enlargement of fuel tank can invite disadvantageous enlargement of the work vehicle.
- Then, it is conceivable to mount, instead of the fuel tank having the above-described conventional construction, a fuel tank configured to cover the upper side of the wheel from its rear side, through effective utilization of the space available above the wheel (the free space between the wheel and the fender). This construction, however, invites increase in the number of components. And, this also requires the trouble of feeding fuel to each individual fuel tank at the time of fuel replenishment.
- The object of the present invention is to provide an improved fuel tank.
- According to one embodiment of the invention, a work vehicle comprises:
- a plurality of wheels including a first wheel;
- a fuel tank disposed above the first wheel;
- wherein the fuel tank includes:
-
- a first portion which is located higher than the highest point of the first wheel in a side view and which also is overlapped at least partially with the first wheel in a top view;
- a second portion disposed forwardly of said highest point of the first wheel and extending downwardly from the first portion so as to extend lower than said highest point of the first wheel, said second portion being in fluid communication with said first portion; and
- a third portion disposed rearwardly of said highest point of the first wheel and extending downwardly from the first portion so as to extend lower than said highest point of the first wheel, said third portion being in fluid communication with said first portion.
- With the above-described characterizing construction, it is possible to increase the capacity of the fuel tank through effective utilization of the space available upwardly of the wheel.
